WebCTCF (CCCTC-binding factor) is a multiple zinc finger protein that exerts diversified functions under different genomic contexts. CTCF was first isolated and cloned on the basis of its ability to bind to highly divergent 50–60 bp sequences within the promoter region of the chicken Myc gene [153].
